Numerical Study on the Effect of the Foil Thickness of Honeycomb on the Energy Absorption of Aluminum Honeycomb Sandwich Panel

Abstract
Sandwich composites are widely used in shipbuilding, aerospace and automobile industry due to its high strength and lightweight. Generally, cellular solids (Honeycomb and Foams) are used as core materials in sandwich composites because of light weight and high energy absorbing capacity. The elastic and plastic properties of the honeycomb are the function of the foil thickness, cell size and density of the honeycomb material. This paper presents the numerical investigation of the effect of foil thickness on the toughness of the aluminum honeycomb sandwich composite. The modeling for the Charpy test has been done by using commercially available software Abaqus. The strain energy for different typologies of sandwich specimens has been compared.
